Answer:</h3>
0.112 deciliter
<h3>
Explanation:</h3>
- Molarity of a solution shows the amount of solute in moles contained in a liter of solution.
- Therefore; Molarity = Number of moles ÷ Volume of solvent in liters
In this case we are given;
Molarity of LiF as 0.88 M
Mass of LiF as 25.5 cg
but, 1 g = 100 cg
Therefore, mass of LiF = 0.255 g
Molar mass of LiF = 25.94 g/mol
We are required to calculate the volume of LiF in deciliter
<h3>Step 1: Determine the number of moles of LiF</h3>
Moles = Mass ÷ Molar mass
= 0.255 g ÷ 25.94 g/mol
= 0.00983 mole
<h3>Step 2: Determine the volume of LiF</h3>
Molarity = Moles ÷ Volume
Rearranging the formula;
Volume = Moles ÷ Molarity
Volume of LiF = 0.00983 mole ÷ 0.88 moles/liter
= 0.0112 L
But, 1 L = 10 DL
Therefore, Volume = 0.112 DL
Thus, the volume of LiF is 0.112 deciliter

For future reference, the periodic table should tell you.
Chemicals are bound together like two pieces of bread
This is the order of activity in decreasing way for the mentioned metals
Mn>Zn>Cr>Fe>Cd>Co>Ni>Pb
Fe is in between Cr and Cd, it is more active than Cd and less active than Cr, so it will displace Cd but not Cr.
Answer:Fe (it will displace Cd, but not Cr)
